What is steam temperature after adiabatic expansion?
lower
What is hotwell in thermal power plant?
In a pow4er house steam is expanded in turbine to get work from it . After expansion of steam it is condensed to reuse. The storage tank in which it is stored ,is called hotwell.
What happens when an electric current passes through steam?
Basically, if you fill a room with steam and pass an electrical current through it... Does anything interesting happen?
Does a steam turbine convert heat energy to kinetic energy?
When one basically sees the flow system in a power plant, then following formula for is-entropic process is important: h+(V2/2) = constant heat energy is related to 'h'(enthalpy). The conversion of 'h' to 'V'(velocity) takes place in a CD (convergent divergent)nozzle, where the steam expands and 'h' is converted into kinetic energy of steam (in turn steam gets a huge momentum)which turn the steam turbine. So basically the kinetic energy for the steam is developed in CD nozzle itself (from decreasing enthalpy which was generated due to heat energy in super heater or the boilers), which turns the turbine.
Which describes a physical change that results from the addition of thermal energy?
Expansion (either of a solid or steam) and evaporation are two of these physical changes.
Nozzle clearance how to steam turbine?
Steam turbine nozzle clearance is the total energy content available in steam. This is through a valve.
What is the conditions of steam velocity while flow through steam nozzle?
Nozzles are designed to increase the steam velocity.
What is the working principle of convergent-divergent nozzle?
A NOZZLE IS A DUCT WHICH CONVERT HEAT ENERGY INTO KINETIC ENERGY.IT INCREASES VELOCITY OF FLUID PASSING THROUGH IT ,AT THE EXPENCE OF PRESSURE. STEAM EXPANDS IN NOZZLE FOLLOW RANKINE CYCLE.FLOW THROUGH NOZZLE IS ISENTROPIC. mritunjay04@gmail.com
What is steam nozzles types of seam nozzles?
1) convergent nozzle 2)divergent nozzle
What is different betweeb single stage and multi stage steam turbine?
In a single stage steam turbine the steam is run through a nozzle to give it maximum velocity, thus the blades move at very high speeds, impractical for some applications, and only some of the energy is used, about 85-90%. In multi-stage or compound turbines the steam goes through a nozzle to increase its velocity, then after going through a set of blades, it is run through another nozzle to bring the steam back up to the correct velocity. After multiple stages there is no longer enough pressure left to up the velocity of the steam. This method increases the efficiency of the turbine and also decreases wear on the components caused by the high speed of a single stage.
What is the working principle of steam turbine?
The Steam Turbine is the one which steam worked pressured Hot and exited then the shaft of the turbine starts to and fro motion due which energy is injected through nozzle in the receiver.
If you downloaded the Sims 3 base game from steam and you want to buy an expansion pack do you have to buy it from steam or can you get it from a store like Wal-Mart?
You can buy an expansion pack from a store like Wal-Mart for a Sims 3 base game bought through Steam instead of needing to buy it through Steam. Simply go to the Origin website and register your products through there and you will receive a Steam key for your game.
How do you transfer steam to one place to another?
Through steam pipes.
How pressure of steam decreases while flowing in a nozzle?
yes
What is a steam turbine?
It is an engine.A steam turbine is a heat engine that uses the expansion of steam passing through stationary nozzles and blades on a shaft to turn the shaft. The steam can move through the turbine axially (one end of shaft to the other end), radially (shaft to outer casing), or tangentially (around the outer edges of the turbine wheel). In an impulse turbine, the steam is expanded in nozzles and pushes the blades. In a reaction turbine the steam is expanded in the nozzles AND in the blades, the reaction of the expansion of the steam pushes away from the blades spinning the wheel in the process. The expansion of the steam is necessary to increase its velocity through the turbine.
What is the difference between isentropic and isenthalpic expansion?
isenthalpic expansion is through PRDS or control valve where entropy changes. Whereas expansion through a steam turbine is isentropic one and enthalpy drops. isentropic expansion is more efficient process as compared to isenthalic one.
Why is convergent-divergent nozzle generally used in steam turbines?
A convergent-divergent nozzle is generally used in steam turbines. This is because it drives generators in producing electricity with the use of turbine rotors with curved axes.
